In this article the Nichols - Hull experiment to measure the momentum of light is described and the Einstein Mass-Energy Equation E = mc2 is derived from first principles using basic concepts from the conservation of momentum.

The Einstein Mass- Energy expression E=mc2 can be derived a number of ways. The derivation in this paper was proposed by Albert Einstein himself and was shared with the author by Dr. Frederick Kaempffer and Dr. George Volkoff in 1984. This paper was originally written in 1984. The manuscript remained lost in the author's papers for several decades until recently rediscovered and published.

It is possible to use the de Broglie Hypothesis, and Einstein's Mass-Energy Equation, to derive a self-consistent estimate for the mass of a proton that relies merely on the length scale of the phenomena we call "the proton". We can also use the proton to estimate the value for the Planck's Constant. This manuscript was written in 1982, but remained lost in the author's library until recently rediscovered. The author would like to acknowledge discussions the author had with the late... Topics: proton mass, self-consistent model, de Broglie hypothesis, Einstein Mass- Energy Equation, Quanum...

In a brilliant paper titled "Does the Inertia of a Body Depend upon its Energy-Content?" published in September 1905 in the German physics journal Annalen der Physik, 17, 1905 ("Ist die Tragheit eines Korpers von seinem Energiegehalt abha¤ngig?") Einstein was able to show that the mass of an object is a measure of its energy content. In this Ï - Physics Initiative in Education module Einstein's Mass-Energy Equation E = mc2 is derived and some of its implications are...
